Polishing Aluminum

Polishing Aluminum

Polishing Aluminum

(OP)
We machine a variety of aluminum parts that we use to build small robots. We anodize the aluminum after finishing the parts with a brushed grain finish. We currently use an orbital sander to remove deep scratches and then finish with ScotchBrite. This is very labor intensive. We tried a Timesaver once, but this left deep grooves in the metal which was unacceptable. Does anyone else have experience with this type of finishing?  

RE: Polishing Aluminum

We cast and machine our own aluminum parts.  Those that are not sand blasted are anodized.  We use vibratory bowls with differant types of media. Drop the part in and wait a few minutes.  Not much labor involved (2 operators for 4 vibratorys).  We have some small ones (3-4 ft dia) made by Sweco that may be of interest.  http://www.sweco.com/Finishing.html

Cheers,

Steve
